Aperture

What do we mean by aperture?

An opening, such as a hole, gap, or slit. noun

A usually adjustable opening in an optical instrument, such as a camera or telescope, that limits the amount of light passing through a lens or onto a mirror. noun

The diameter of such an opening, often expressed as an f-number. noun

The diameter of the objective of a telescope. noun

The act of opening out or unfolding. noun

An opening; a hole, orifice, gap, cleft, or chasm; a passage or perforation; any direct way for ingress or egress. noun

In geometry, the space between two intersecting right lines. noun

In optics, the diameter of the exposed part of the object-glass in a telescope or other optical instrument. noun

The act of opening. noun

An opening; an open space; a gap, cleft, or chasm; a passage perforated; a hole. noun

The diameter of the exposed part of the object glass of a telescope or other optical instrument. noun

An opening; an open space; a gap, cleft, or chasm; a passage perforated; a hole; as, an aperture in a wall. noun

Something which restricts the diameter of the light path through one plane in an optical system. noun

The diameter of the aperture (in the sense above) which restricts the width of the light path through the whole system. For a telescope, this is the diameter of the objective lens. e.g. a telescope may have a 100 cm aperture. noun

The (typically) large-diameter antenna used for receiving and transmitting radio frequency energy containing the data used in communication satellites, especially in the geostationary belt. For a comsat, this is typically a large reflective dish antenna; sometimes called an array. noun

The maximum angle between the two generatrices. noun

A device that controls amount of light admitted noun

An man-made opening; usually small noun

A natural opening in something noun

An opening, gap, or hole, usually small and narrow

Something which restricts the diameter of the light path through one plane in an optical system.

The diameter of the aperture (in the sense above) which restricts the width of the light path through the whole system. For a telescope, this is the diameter of the objective lens.

(communications) The (typically) large-diameter antenna used for receiving and transmitting radio frequency energy containing the data used in communication satellites, especially in the geostationary belt. For a comsat, this is typically a large reflective dish antenna; sometimes called an array.

(of a right circular cone) The maximum angle between the two generatrices.
